Description
SK hynix Unbuffered Small Outline DDR4 SDRAM DIMMs (Unbuffered Small Outine Double Data Rate Synchronous
DRAM Dual In-Line Memory Modules) are low power, high-speed operation memory modules
that use DDR4 SDRAM devices. These DDR4 SDRAM Unbuffered Small Outline DIMMs are intended for use
as main memory when installed in systems such as micro servers and mobile personal computres.
